Applicationledjl'une 20, 1914. Serial No. 846,818.

To all 'whom t may cont-em Be it known that I, ROBERT O. ATKINSON, acitizen of the United States, and resident of Eden Vale, in the countyof Santa Clara and State of California, have invented certain new anduseful Improvements in Baling-Presses, of which the following is aspecification.

My invention relates broadly to balingpresses, and more particularly tothat class of presses in which the plunger travels vertically upward tocompression.

In operating the type of presses herein considered there is a great lossof time due to the accumulation of material beneath the filling platformand the press proper, which must" be frequently cleared away, and to thefact that when the feed-door is closed and the plunger advancing, thefeeder men must 4stand prepared to throw forward the.

next charge of material to be pressed the moment the plunger is dropped.

It is one object of my invention to prevent any great accumulation ofmaterial under the filling platform and the press.

Another object is to enable the feeder men to continue to throw materialforward ready for .the next stroke of the plunger and thus relieve thetension of waiting and also economize greatly. in the operation of themachine.

A third object is to still further safeguard the men working on the feedplatform, and a fourth object is to prevent dust and fine matter frombeing blown through the press chamber and up into the faces of the menon the discharge platform.

A final object of my invention is to produce an improvement that willaccomplish these objects that can be adapted for use on machines of thistype already in use as well as be incorporated in new machines whilebuilding.

The invention will be best understood from a consideration of thefollowing detailed description, in connection with the accompanyingdrawings forming a part of this specification, in which Figure 1 Iis avertical cross section through a baling-press with my improvementattached thereto, parts being broken away. Fig. 2 is a plan view of theroller frame and roller in position. Fig. 3 is a detail elevationshowing the manner of carrying the roller frame, parts being brokenaway. Fig. 4 is a-side elevation of detail 3. Fig. 5 is a frontelevation of the supporting plate. Fig. 6 is a front elevation of thepress-chamber guard-plate. Fig. 7 is a detail section showing manner ofattaching the presschamber guard-plate to the supporting plate, and thesupportingplate to the plunger head, parts being broken away. Fig. 8 isa detail side elevation showing construction of the bar carrying theroller frame and roller, parts being broken away. Fig. 9

is a detail section showing the manner of attaching the curvedguard-plate to the feed-door, parts being broken away. Fig. 10 is aperspective view of the curved guardplate -and the braces attachedthereto. Fig.

similar parts throughout the several views.

Referring now to the drawings, 1 indi- Cates the press-chamber, 2 thebale-chamber and 3 the supporting framework of a bal-' ing-press inwhich the plunger 4 travels vertically upward to compression. Thebaledischarge door is shown at 5 and discharge platform at 6. Afeed-door is shown at 7 opening outwardly from the top and hinged at thebottom as 8, sides 8a attached to said baling-press forming a chute inwhich said feed-door 8 operates. The bottom of said press-chamber 1 isshown at 9. At 38 are shown the slots through which the plunger 4 isconnected to arms not shown by bar 4". At 10 is shown a metallic platecovering said bottom 9. All of these above mentioned parts, and themechanism used in operating the press, not shown, constitute the machineupon which my improvement is built.

An essential part of my improvement is a platform, as 11, supported by aframework 12, preferably built of angle-irons braced and bolted togetherhavin I beams, as 1 2, rest-ing' thereon, `upon whic floor 12b is laid.Said framework 12 rests upon, and 1s secured to, timbers 13 which arefastened by bands 14 to the two projecting arms 15, said arms 15 beingan integral part of supporting framework 3 of the baling-press. Saidplatform 11 is set out from the press proper a s uflicient distance toallow door 7 to swing op'en until its upper edge will just clear thelower edge of said-platform 11 as shown at 16., To the upper edge offeed-door 7 I attach a curved metallic guard-plate 17. The upper edge ofsaid guard-plate 17 is bent downward a distance, as 18, formin a flangethereon, said flange being drille at the. proper intervals to receivebolts. Said guard-plate 17 is reinforced by metallic ribs as 19 placedparallel to the movement of said. door, and ribs 19a runningtransversely thereto, and supported by braces 20 fastened thereto. Inattaching said uard-plate 17 to the upper ed e of said eed-door 7 flange18 is slipped own between the inner lining 21 and reinforcements 22 ofsaid feeddoor 7, curved ribs 19 are bent downwardly at their ,upper endsasshown at 23 to engage the voutside ofsaid feed-door 7 and then thewhole held securely in place by bolts 24 passing therethrough. Braces20. are securely bolted to said door 7 as shown at 25, guardplate 17thus effectually closing the aperture that would otherwise exist betweenthe platform 11 and the baling-press proper when feed-door 7 is closed.At 26 is shown a vertically movable press-chamber guard reinforced andstiilened by ribs as 27. At 28 is shown a vertical slot cut in saidpresschamber guard adapted to engage a bolt 29 set in supporting plate30, Supporting plate 30 is securely bolted to angle iron 31 which is inturn securely fastened to the under side of plunger 4 close to the outerlongitudinal edge thereof as' shown in'detail'in Fig. "yl, the side ofthe press facing the feed-platform being considered the outer side. Inorder to permit the free vertical movement of presschamber lguard 26 aslot 32 is formed in the bottom 9 of press-chamber 1. Said slot 32 isformed by cutting back said bottom 9 the.

required distance and building in an additional I beam to support thesame asshown at 33. It is of course essential that some means be used toprevent the lower edge of said press-chamber guard 26 from being forcedinto said press-chamber when vit is drawn upward and out of said slot32. To accomplish this result a roller-frame 34 is used, made of angleiron and adapted to reciprocate in saidpress-chamber 1, and having aroller 35 revolubly mounted in its outer side uponan axial'rod 36. Thedimensions of said roller-frame 34 are such as to. keep the roller 35againstthe inner Asur'- facel of saidpresschamber guard; 26 and1,1ae,oso

hold the same at all times in line with said slot 32. When said plunger4 has reached the end of its stroke said press-chamber guard 26 is drawna distance above and free of said slot 32, therefore it is necessarythat of to receive said roller-frame 34 so that thev same will not bestruck by the fall of the plunger 4. Both ends of said supporting bar 37project a distance through the guide slots 38 in the two side Walls ofpress-chamber l. Passing under said ends'of said supporting bar 37 aresupports 39. Passing through said supports 39 and bolted thereto arethetwo ends of. lifting 'rods 40, said rods 40 being carried upward throughguides 41 attached to the walls of said press-chamber 1, and over saidarms 4"L attached to plunger 4 by which said plunger 4 is operated.Washers 42 and 43 respectively are pinned in their required respectivepositions on said rodsl 40 and above guides 41, springs 44 beingpreviously placed in position on said rods 40 and between said washers42 and 43.

Assuming now that the plunger is at the end of its upward strokeand'allowed to fall preparatory to compressing a new charge.v Thesupporting framework of a bal-ing-press Ais comparatively low, so thatvif the press-chamber guard 26 is bolted immovably to plunger 4 a slotwould have to be prepared .in the ground into which said guard 26 woulddrop when the plunger 4 falls to the bottom 9 of press-chamber 1.

Toobviate the necessity of cutting a slot in the ground, slot 28 is cutin the upper portion of guard 26 so that when said presschamber guard.26 falls with said plunger 4 and strikes the ground, said plunger 4continues to descend the full length of its stroke the bolt 29 movingdownward in said slot 28 the required distance. When said plunger-Lagain advances it draws said guard 26 upward and finally completely outof saidslot 32. Just before the point when said guard 26 passes free ofslot 32, bar 4 on plunger 4 engages rods 40 thus drawing roller-frame 34and roller 35 upward and thus holding said guard 26 in position until,again dropped into said slot 32. Springs 44 are inserted to break thefall of roller-frame 34. It will thus be seen that press-chamber guard26 always closes the opening to said press-chamber 1 when said plunger 4is not in position to receive a charge. Even though door 7. be open a ofplunger 4. n order to give greater freedom to the movement of saidpress-chamber guard 26 two vertical slots as 26l are cut in the upperortion and near the edges thereof adapte to engage bolts as 26e movingfreely 1n horizontal slots 26b in supporting plate 30. These crossedslots 26a and 26" 4with bolts 26c operating freel therein serve topermit a sidewise motion o said guard 26 without lbreaking or bucklingthe same. ln building a new machine a vertical ide slot, as 45, may beformed in each si e of said machine and press-chamber guard 26 adaptedto move therein, in which case said roller-frame `and roller 34 and 35respectively would not be required, and a guard of two or more sectionsas shown in Figs. 12 and 13 may be used. In the latter case a slide 46on one section engages a lug 47 on the next lower section. It is not mydesire to be limited to the exact construction of my improvementdescribed in this specification, as many minor changes in constructionand operation may be made without departing from the spirit of myinvention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is,-
